Volunteers: No Healthy Volunteers

Inclusion criteria

1. Patients ≥19 and ≤ 80 years of age at Visit 1 (Screening) in accordance with American Diabetes Association (ADA) guidelines
2. Patients who had received a stable dose of Drug A for at least 8 weeks prior to Visit 2 (Run-in vis it).
3. In case of antidiabetic concomitant medications, patients who have maintained up to 2 oral antidiabetic drugs [OADs]) without changing regimen/dose/dosage at least 8 weeks prior to Visit 2 (Run-in visit).
4. Patients with FPG of <270 mg/dL at Visit 1 (Screening) (FPG result at Visit 1 will use local laboratory results)
5. Body Mass Index (BMI) 18.0-40.0 kg/m2.

Exclusion criteria

1. Patients with type 1 diabetes mellitus (T1DM), congenital diabetes mellitus (DM), or secondary diabetes as follows:

   1. Diabetes caused by Cushing's syndrome and acromegaly.
   2. Patients with fasting C-peptide <0.70 ng/mL (0.23 nmol/L) are excluded if the Investigator cannot rule out T1DM based on the clinical assessment.
   3. Patients with a history of T1DM or a history of ketoacidosis or patients assessed by the Investigator as possibly having T1DM confirmed with a C-peptide <0.70 ng/mL (0.23 nmol/L).
   4. History of other specific types of diabetes (eg, genetic syndromes, secondary pancreatic diabetes, diabetes due to endocrinopathies, drug- or chemical-induced, and post-organ transplant).

2. Patients receiving SGLT2 inhibitors, GLP-analogues, thiazolidinediones, or sulfonylureas (at Screening and Run in).

3. At Visit 1 (Screening), patients with a history of the following:

   1. Patients who had experienced severe hypoglycemia within 24 weeks prior to Screening or who had experienced hypoglycemia at least 3 times a week within 8 weeks prior to Screening.
   2. Patients with a history of diabetic ketoacidosis or coma from hyperosmolar hyperglycemic syndrome within 24 weeks.
   3. Patients with a history of myocardial infarction, unstable angina, arterial revascularization, stroke, transient ischemic attack, within 3 months prior to Screening.
   4. Patients with New York Heart Association (NYHA) Class III, IV congestive heart failure or arrhythmia requiring treatment. History of dose modification of a treatment for thyroid dysfunction within the past 6 weeks (If patients have been on a stable dose from before enrollment to the study, concomitant administration is allowed. Dose reduction for stable condition is allowed).
   5. Patients who had a surgical operation within 4 weeks (excluding minor surgeries without restriction on food and fluid intake) or who are scheduled to have a significant surgery during the study period.
